My 20 week old Ameraucana, is acting strangely. She's was eating and drinking but is laying down in the yard and her back end is going up and down. I don't know what hens are suppsoed to look like when they lay an egg but could that be what she's trying to do? She's been moving slowly all day. I checked her vent and it's slightly open. After checking it, she had white diarrhea, just a small amount. Should I be concerned or is this possibly her showing signs of laying an egg? VIDEO Update*** Day 2 and she's worse. She's not eating and isn't moving much. Tail still moving up and down and she seems more lethargic.
